Imaging spectrum of gastrointestinal stromal tumor |
p. 143 |
Binit Sureka, Mahesh Kumar Mittal, Aliza Mittal, Mukul Sinha, Brij Bhushan Thukral DOI:10.4103/0971-5851.138964 PMID:25197176Gastrointestinal stromal tumors (GISTs) were first described by Clark and Mazur in 1983 for smooth muscle neoplasms of the gastrointestinal tract differentiating them from leiomyoma, leiomyosarcomas and neurogenic tumors. GISTs can arise from the bowel, peritoneum, omentum or retroperitoneum. This article reviews the computed tomography imaging features of primary GISTs, response to treatment and highlights data on predicting the outcome to chemotherapeutic drugs on imaging. |

Expression of phosphatase and tensin homolog, epidermal growth factor receptor, and Ki-67 in astrocytoma: A prospective study in a tertiary care hospital |
p. 149 |
Rajdeep Saha, Uttara Chatterjee, Sonali Mandal, Kaushik Saha, Sandip Chatterjee, Samarendra Nath Ghosh DOI:10.4103/0971-5851.138983 PMID:25197177Background: Though the tumor grade is a key factor influencing the choice of therapies, particularly determining the use of adjuvant radiation and specific chemotherapy protocols, role of abnormality in phosphatase and tensin homolog (PTEN) expression and variation in epidermal growth factor receptor (EGFR) labeling index (LI) and Ki-67 LI in survival and clinical outcome have been studied by many researchers in the recent past. Aims: The aim was to evaluate the expression of PTEN, EGFR and Ki-67 in different grades of astrocytic tumors by means of immunohistochemistry and to judge their role in overall survival (OS). Materials and Methods: This study was conducted on 57 cases of different grades of astrocytomas. Expression of PTEN, EGFR and Ki-67 was assessed by immunohistochemistry on formalin fixed and paraffin-embedded sections and the OS was evaluated by Kaplan-Meier survival curves and log-rank test for 2.5 years from the date of primary resection. Results: Most of the tumors (59.6%; 34 cases out of 57) displayed WHO Grade IV features. Distribution of age, EGFR LI and Ki-67 LI expressed strong positive (≥0.5) correlation with the grade of tumors. However, the PTEN positivity was inversely related with the grade of the tumors. Lower WHO grades, lower values of Ki-67 LI, EGFR LI and PTEN positivity were associated with better survival. Conclusion: Expression of PTEN, EGFR LI and Ki-67 LI should be combined with the basic histopathological features including WHO grade to predict the prognosis and therapeutic outcome. |

Status of salivary lipid peroxidation in oral cancer and precancer |
p. 156 |
Shishir Ram Shetty, Subhas Babu, Suchetha Kumari, Pushparaja Shetty, S hruthi Hegde, Renita Castelino DOI:10.4103/0971-5851.138990 PMID:25197178Introduction: Lipid oxidation gives rise to number of secondary by-products. Malondialdehyde (MDA) is the principal and most widely studied product of polyunsaturated fatty acid peroxidation. This aldehyde is a highly toxic molecule and should be considered as more than just a marker of lipid peroxidation in oral carcinogenesis. Materials and Methods: Salivary malondiadldehyde was evaluated in 65 healthy controls (HC), 115 subjects with oral, potentially malignant disorders (PMD) and 50 subjects with oral squamous cell carcinoma (OSCC) using the Thiobarbituric-Trichloroacetitic acid (TBA-TCA) method. Results: A consistent elevation in the levels of salivary MDA was observed in HC with tobacco related habits, subjects with PMD and subjects with OSCC. The elevation in the salivary MDA was significant (P = 0.001) in the groups PMD and OSCC and group OSCC when compared to HC. Conclusion: The significant and encouraging findings of this study thus validate and reinforce that salivary malodialdehyde analysis can be used as an efficient, noninvasive tool for the early diagnosis of PMD and OSCC for planning comprehensive treatment protocol. |

Cytological study of palpable breast lumps presenting in an Indian rural setup |
p. 159 |
Smita Balwantrao Sankaye, Suyrakant Dattatreya Dongre DOI:10.4103/0971-5851.138993 PMID:25197179Introduction: Benign as well as malignant breast lesions are quite common in Indian population. It is the second most common cancer site after cancer cervix. Fine-needle aspiration cytology (FNAC) is safe, reliable, and time saving outdoor procedure with little discomfort to the patient. FNAC is useful in diagnosis and further planning of treatment without need for biopsy. The current study was carried out with aims of studying the frequency of various breast lesions on FNAC in a rural area in India and its histopathological correlation. Materials and Methods: This was 2 years prospective study carried out from May 2010 to April 2012. Physical examination of breast mass by palpation was done. Smears were stained with May-Grunwald Giemsa and Papanicolaou stain. Results: Of the 225 cases, 131 were in the benign category and 65 belonged to the malignant category, while the cytology study of 13 cases was unsatisfactory. Seventy-six cases were available for histological correlation. Of 29 cytological benign cases, 26 were confirmed as benign, but 3 turned out to be malignant. Out of 36 cytological malignant cases, 35 were confirmed as malignant. FNAC was 88.37% sensitive and 96.42% specific in diagnosing malignant lesions. Conclusion: Fine-needle aspiration cytology is a rapid and effective method for the primary categorization of palpable breast lumps into benign, malignant, atypical, suspicious, and unsatisfactory categories. Benign breast lesions are common than malignant lesions. Histological correlation indicated FNAC to be a good diagnostic tool. |

Is there any role of mast cell density and microvessel density in cervical squamous cell carcinoma? A histologic study with special reference to CD-34 immunomarker staining |
p. 165 |
Santosh Kumar Mondal, Senjuti Dasgupta, Palash Kumar Mandal, Shankha Chatterjee, Debdutta Chakraborty DOI:10.4103/0971-5851.138994 PMID:25197180Background: Mast cells are involved in induction of angiogenesis in the early-stages of tumor development and in modulating blood vessel growth in the later stages of tumor progression. Aims and Objectives: This study was carried out to evaluate the association between mast cell density (MCD) and microvessel density (MVD) in carcinoma in situ (CIS), microinvasive carcinoma (CA) and invasive squamous cell CA of cervix. Materials and Methods: Six cases of CIS, four cases of microinvasive CA and 38 cases of invasive CA were studied over a period of 2 years from August, 2011 to June, 2013. Ten control samples were included in the study. Routine histologic examination was done. Toluidine blue stain was used for MCD determination. Immunohistochemical analysis with CD-34 was done for assessing MVD. Student's t-test was used to calculate the statistical significance of MCD and MVD. Results: Both MCD and MVD increased from normal samples through CIS to invasive cervical CA. In the four cases of microinvasive CA, the MCD and MVD were more than that of the control samples, but less than that of the six cases of CIS. Conclusion: There is a correlation between mast cell accumulation and angiogenesis in CIS, microinvasive CA and invasive cervical squamous cell CA. MCD and MVD in invasive CA exceed those in CIS and microinvasive CA. It gives us an opportunity to postulate that therapeutic strategies against mast cell mediators and angiogenesis may be of benefit in patients of early-stage cervical CA. |

Spectrum of nonhematological pediatric tumors: A clinicopathologic study of 385 cases |
p. 170 |
Rajpal Singh Punia, Irneet Mundi, Reetu Kundu, Geetanjali Jindal, Usha Dalal, Harsh Mohan DOI:10.4103/0971-5851.138995 PMID:25197181Background: The aim of this study is to understand the epidemiology of tumors in children in our region due to a paucity of studies on the histologic review of the childhood tumors in general and benign tumors in particular. Materials and Methods: The records of all the tumors diagnosed histopathologically in children <14 years of age during a period of 8-year (2005-2012) were reviewed. Results: A total of 385 tumors were seen in the age range of 1 month-14 years with 231 (60%) in boys and 154 (40%) in girls. Highest number of cases, 224 (58.18%) were in the age group of 10-14 years. Benign tumors comprised 275 (71.43%) cases while the malignant tumors accounted for 110 (28.57%) cases. In benign tumors, vascular tumors were in majority with 68 cases, while in malignant category bone tumors were most common with 36 cases. Conclusions: Although the exact incidence rate cannot be provided by this hospital-based study, the information is useful in showing patterns of childhood tumors. We included both benign and malignant tumors, while most of the studies in the past have focused mainly on malignant tumors in children. |

American Society of Clinical Oncology 2014: Updates in breast and gastrointestinal cancers |
p. 176 |
Shaheenah Dawood DOI:10.4103/0971-5851.138997 PMID:25197183The last two decades have been very exciting in the realm of breast and GI oncology with a plethora of new information that has significantly impacted clinical practice. From the use of anti HER 2 agents in both the adjuvant and metastatic settings of breast cancer to the use of anti EGFR agents in the metastatic setting of colorectal cancer we have seen some significant advances in the treatment of these diseases. This year at ASCO 2014 data were presented that attempted to answer important clinical questions faced by a community oncologist in the clinic. This review focuses on important data presented for both breast and GI cancer. |

Liver metastasis in an adolescent treated for third ventricle germ cell tumor |
p. 181 |
Rikki R John, Arul Premanand Lionel, Venkatramani Sitaram, Leni G Mathew DOI:10.4103/0971-5851.138999 PMID:25197184Systemic dissemination of intracranial germ cell tumors (GCTs) occur only in 3% of cases and the common sites are bone, lungs, and lymph nodes. Metastasis to the liver is rare. As far as we could find, only six cases of liver metastasis of intracranial GCTs have been reported so far. We report an adolescent girl who presented with hepatic relapse 2 years after successful completion of treatment of intracranial GCT. She was treated with chemotherapy and right hepatectomy and is doing well 30 months after treatment for the metastatic disease. |
